STRIKINGr-BAG.

Patented Dec. 28,' 1909.

Serial No. 473,436.

\ gymnastic apparatus and more particularly to that class known asstriking-bags.

The object of my improvements is the provision of a device of thisnature which will afford an extended range of exercisev for v musculardevelopment and the promotion of agility in the user.

rlheinvention consists in the novel construction and adaptation ofdevices, asavill be hereinafter described and claimed.

Tn the accompanying drawings, Figure 1 is alfront elevational view ofapparatus embodying'my invention. Fig. 2 is a side View of the same.Fig. 3 is a horizontal section taken through 3 3 of the preceding views.

Inthe drawings, the reference numeral 5 designates a board,-or anequivalent, which is arranged to be approximately verticaland is securedat its lower end by an attachment to an underneath support, such as afloor. This attachment is desirably comprised of two metallic angle-bars6 which are clamped to the board by nutted screw-bolts 7 extendingthrough the board and the upturned anges of said bars. The angle-barsare also rigidly secured to said support, as by bolts.

Adjacent to the upper end of the board, it is secured against horizontalmovement by being housed between rollers 8 and 9 which are desirablycovered with a peripheral facing of rubber or other elastic material andare disposed to bear respectively against the front and rear faces ofthe board. The rollers are mounted for rotation upon transverselyarranged rods 8 and 9 extending between and connected at their ends withthe horizontal members 10 of a frame. The frame members 10 are providedat the rear with sockets 11 through which respectively extend postelements 12 of brackets which are adapted to be secured to a house wallor other suitable support, as by screws passed through wall-plates 13upon the outer ex tremities of rearwardly extending arms 1a. The framewhich carries said rollers is adapted to be secured at variouselevations,

as by set-screws 15 extending through screwthreaded-holes in the socketmembers to impinge against the bracket-posts 12.

16 is a striking bag` which, as shown in Fig. 3, is comprised of a sack17 of leather, or other tough and flexible material, and isprovidedfwith a filling 18, suoli as hair. This bagis desirably of anoblong configuration with a width approximating that of the board and isprovidedl with eyes 19 which are secured to the bag by straps 20. Saideyes are disposed in couples, and eaeh'pair thereof is arranged in ahorizontal plane. The office of .these eyes isto afford means for theengagement of straps 21, wherewith the bag is lashed to the board and,for the better securement of the bag, pairs of spaced holes 22, areprovided near the lateral edges-of the board and through selected of theholes said strapsl are extended. Advantageously, the straps are eachdoubled to provide loops 2l to receive'the aforesaid eyes and therespective'straps are provided with a buckle 23 upon one end tovadjustably engagethe perforated other end of its strap and fastening atthe rear of the board. Said pairs of holes 22are'spaced apart tocorrespond withthe spacing of the bagstraps and, preferably, at leastone pair of such holes in excess of the number of straps is provided forthe bag thus enabling the bag to be lashed to the board at variousheights for the accommodation of the user. For example, an adult securethe bag in a more elevated position than would be suitable for ajuvenile who would utilize the lower holes with the bag at a lowerheight.

To use the invention the bag is struck from the front either directly orin oblique lines to the plane of the board whereupon the resiliency ofthe board allows the same to be sprung rearwardly with the bag, asindicated by the broken lines in Fig. 2, the elasticity of the boardthen asserting itself to cause the board to rebound forwardly of itsnormal plane, provided that the user does not overcome such rebound bycounter blows. By reason of the bottom of the board being fixedlysecured it is obvious that the top thereof is drawn downwardly tocompensate for whatever bending movement is given the board and incorrespondence to the force of the blow delivered against the bag. The

provision of the rollers in the frame-support would, in practice, employsuch holes as to for the upper portion of the board offers littlerestraint to such bending of the board. The effective elasticity of theboard may be graduated by lowering or raising the rollercarrying frame.Should the filling of the bag through hard usage settle toward thebottom of the bag then the latter may be reversed. The bag, as beforementioned, may be likewise secured to various adjusted heights to suitthe purposes of the user.

As a means for the development of the muscles which are brought intoplay in boX- ing, this invention is peculiarly valuable and is adaptedfor use either in the home or in gymnasimns.

l/Vhat I claim, is-

l. In an apparatus of the class described, an upright board, means forfixedly securing said board at its lower end, means including tworollers for supporting the upper portion of the board therebetween, anda striking-bag secured to the board intermediate the two aforesaidmeans.

2. In an apparatus of the class described, a board, a striking-bag,strap connections for securing the bag to the board, and means foradjustably securing the board in an upright position.

3. In apparatus of the class described, an upright board, a striking bagdetachably connected to said board, means for connecting the lower endof the board to a fixed support, and adjustable means for connecting theupper end of the board to a support.

at. In apparatus of the class described, an upright board which islXedly secured at its lower end, a bracket arranged for securement to awall and provided with an upright post, a frame slidably connected tosaid post, rollers rotatably carried by the frame and spaced apart toaccommodate said board therebetween, a striking-bag, and means forsecuring said bag to the board.

5. In apparatus of the class described, an upright spring-board, astriking-bag detachably connected to said board, means for Xedlyconnecting the lower end ofk the board to a Xed support, and adjustablemeans which are located above the bag for preventing the tilting of theboard from an upright position.

6. In apparatus of the class described, a striking-bag, an uprightsupport for said bag, a means fixedly securing the lower end of thesupport, and a means for securing the upper end of the support againsttilting, said means being arranged to allow longitudinal movement to thesupport with respect to the means.

7. Inapparatus of the class described, a striking-bag, a support forsaid bag, means for securing the respective ends of said support, one ofsaid means being arranged to allow longitudinal movement to the supportwith respect to said means.

8. In apparatus of the class described, a spring-board arranged in asubstantially upright position, a means for iXedly securing the lowerend of the board to a fixed support, a bracket arranged to be secured toa vertical support, a frame movable vertically upon the bracket, meansto secure said frame in adjusted positions `with respect to saidbracket, two rollers rotatably mounted in said frame and disposed toreceive the board therebetween, and a striking-bag secured to the board.
